I have an 04 Z71 Tahoe w/ ~184k. I replaced these when I replaced the plugs @ 179k. By doing both, I have noticed an increase in my mpg's by about 1-1.5/mpg. Overall, great product and you can't go wrong with ACDelco.

Installed this in a few hours with spark plug change. It was my first time attempting to do this for my 2004 chevy avalanche and everything worked out in the end. The biggest problem is getting room to pull off the boots from the spark plugs near the fire wall and hard to reach areas but I got it done. It seems like I have more power and probably better mileage but I haven't calculated how much if any yet.

I recently purchased these spark plugs to replace the ones I had been using during my routine maintenance. I wanted to try these to see how they compared to another brand I was using. So far, they have performed as expected.

Happy to help with your question John! These spark plug wires will be a solid wire core, according to AC Delco the type of wire core varies depending on the model of the vehicle. When doing your tune up service be sure get some Dielectric Tune-Up Grease (Part No 09980).

Q:

In the description it says "ALL MAKES; FOR COILS STAMPED 12558693". Where do I find what coil # I have? I have looked and don't see a #.

We will need more information including the year, make, model, and engine size of your application before we can make a suggestion. Please call us at 1-877-ADVANCE (238-2623) and we would be more than happy to further assist you.

A:

number is on the bottom of the coil...you'll need a small mirror and a flashlight...

Ans: 1. Open the hood and locate the spark plug wires. They can be black, blue, red or orange. Most are black. The number of spark plug wires most often corresponds to the number of cylinders your engine has.

2.Open the box of new spark plug wires. If the new wires aren't labeled ("1," "2" and so on), lay them out in order of length.

3.Start at one end of the engine and remove only the first spark plug wire: Pull on the boot (at the end) of the plug wire until it pops off.

4.Follow the wire to its other end, where it's plugged into the distributor cap. Remove the wire from the distributor cap by pulling on the end of the wire.

5.Check the spark plug. A good spark plug will be lightly coated with greyish brown deposits. If heavy deposits are present, if the spark plug is black, or if the electrode or core nose are damaged, replace the spark plug (see "Replace Spark Plugs" under Related eHows).

6.Note that most cars have small plastic pieces with slots that hold the wires in place so they don't rub against each other or rest on any part of the engine. Be sure to put the plug wires back into their slots to ensure longer life.

7.Replace with a new spark plug wire of the same length or number. The plug wire will make a quiet "pop" when it snaps on the spark plug.

8.Continue with the next spark plug wire, always taking one off at a time and replacing with a new wire until you've replaced all of the wires.

Q:

Does the set include all eight wires or is the price listed for just one wire?
